Diodes Incorporated 74LVC1G97FW4-7

Overview

74LVC1G97FW4-7 from Diodes Incorporated is a single three-input configurable multiple-function logic gate in X2-DFN1010-6 package, supporting MUX, AND, OR, NAND, NOR, inverter, and non-inverting buffer functions via 3-bit input pattern selection. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, features 5.5V-tolerant inputs, and includes IOFF circuitry for partial power-down protection. It is used in voltage-level shifting and power-down signal isolation within compact portable electronics.

For engineers reviewing the 74LVC1G97FW4-7 datasheet, 74LVC1G97FW4-7 pinout, 74LVC1G97FW4-7 application, or 74LVC1G97FW4-7 equivalent, this device offers configurable logic in a 1.0mm × 1.0mm DFN package with Schmitt-trigger input hysteresis, 6.3ns max propagation delay at 3.3V, and guaranteed operation from –40°C to +125°C - critical for space-constrained, mixed-voltage embedded designs.

Technical Context

This device implements a programmable combinational logic function using three digital inputs (IN0, IN1, IN2) to select one of eight truth-table outputs mapped to Y. Its internal architecture supports reconfigurable logic without external programming - configuration is static and determined solely by input voltage levels during operation.

The input stage includes Schmitt-trigger action with hysteresis (0.32–1.40V depending on VCC), enabling noise immunity in noisy environments. The IOFF feature disables output current flow when VCC = 0V, preventing back-drive damage in partial-power-down systems - a key requirement for hot-swap and battery-backed subsystems.

FAQ

Can 74LVC1G97FW4-7 be used as a level shifter between 5V and 1.8V logic domains?

Yes - its 5.5V-tolerant inputs accept 5V signals while operating from 1.8V VCC, and its push-pull output swings rail-to-rail (0V to 1.8V). No external resistors or direction control are needed. However, output voltage is limited to VCC, so bidirectional translation requires additional components.

What is the minimum recommended decoupling capacitance for stable operation at 100MHz toggle rate?

A 100nF X7R ceramic capacitor placed within 2mm of the VCC and GND pins is required. For >50MHz operation, add a 1nF capacitor in parallel to suppress high-frequency supply noise; the X2-DFN1010-6's low inductance pad layout supports this dual-capacitor strategy.

Does the Schmitt-trigger input behavior affect timing analysis in synchronous designs?

No - the hysteresis applies only to input threshold stability and does not alter propagation delay (tpd) specifications. All timing parameters (including tPLH/tPHL) are measured using standard VIH/VIL thresholds per JEDEC JESD8-12; Schmitt action improves noise margin without impacting setup/hold timing windows.

Is the exposed thermal pad on X2-DFN1010-6 electrically connected internally?

No - the exposed pad is a thermal slug only, with no internal electrical connection. It must be soldered to a dedicated thermal copper pour (minimum 25mm²) for optimal θJA performance, but may remain floating if thermal requirements are relaxed.
